Det er noen som sier at å spise “alt med måte” er sunt. Nå viser forskning at det generelle rådet om et variert kosthold og “alt med måte”-kostrådet ikke er sunt likevel, er forbundet med dårligere kvalitet på kostholdet og kan bl.a. føre til økt risiko for diabetes type 2.
Et variert kosthold kan knyttes til lavere kostholdskvalitet og dårligere metabolsk helse, ifølge forskere ved The University of Texas Health Science Center at Houston (UTHealth) and the Friedman School of Nutrition Science and Policy at Tufts University. Studien ble publisert i PLoS ONE.
Forskerne konkluderer med:
“Our findings provide little evidence for benefits of diet diversity for either abdominal obesity or diabetes. Greater dissimilarity among foods was actually associated with gain in WC. These results do not support the notion that “eating everything in moderation” leads to greater diet quality or better metabolic health.”

“‘Eat everything in moderation’ has been a long-standing dietary recommendation, but without much empiric supporting evidence in populations. We wanted to characterize new metrics of diet diversity and evaluate their association with metabolic health,” said Marcia C. de Oliveira Otto, Ph.D., first author and assistant professor in the Department of Epidemiology, Human Genetics and Environmental Sciences at UTHealth School of Public Health.
At ten years, higher diet quality was associated with about a 25 percent lower risk of developing Type 2 diabetes.
“An unexpected finding was that participants with greater diversity in their diets, as measured by dissimilarity, actually had worse diet quality. They were eating less healthy foods, such as fruits and vegetables, and more unhealthy foods, such as processed meats, desserts and soda,” said Otto. “This may help explain the relationship between greater food dissimilarity and increased waist circumference.”
“Americans with the healthiest diets actually eat a relatively small range of healthy foods,” said Dariush Mozaffarian, M.D., Dr.P.H., senior author and dean of the Friedman School of Nutrition Science and Policy at Tufts University in Boston. “These results suggest that in modern diets, eating ‘everything in moderation’ is actually worse than eating a smaller number of healthy foods.”
